Abstract
An apparatus and method for estimating resource consumption of a household device, e.g., an appliance. The method comprises determining a resource demand profile for a household device for a given time period, the resource demand profile associating, for the given time period, a device state of the household device with a total resource demand for the household. In one embodiment, the apparatus can be incorporated into an energy management system, where the apparatus collects data from each of the appliances in a household as well as from a resource meter.
Claims20
An apparatus configured to monitor resource consumption of an appliance in a household, said apparatus comprising:
- a processor;
- a memory coupled to the processor;
- and
- one or more executable instructions stored on the memory and configured to be executed by the processor, the one or more executable instructions comprising instructions for:
- determining a resource demand profile for a household device for a given time period, the resource demand profile associating, for the given time period, an operating state profile of the household device with a total resource demand profile for the household.
An apparatus, comprising:
- a processor;
- a memory coupled to the processor;
- and
- one or more executable instructions stored on the memory and configured to be executed by the processor, the one or more executable instructions comprising instructions for:
- receiving data from a household device and a resource meter that measures a total resource demand for the household;
- and
- applying a least squares method to the data to determine a resource demand profile for the household device,
- wherein the resource demand profile associates, for a given time period, an operating state profile for the household device and a total resource demand profile.
A method, comprising:
- at a remote device comprising a processor and memory:
- determining a resource demand profile for a household device for a given time period, the resource demand profile associating, for the given time period, an operating state of the household device with a total resource demand profile for the household.
